Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for synthesizing novel bisphenol S derivative polysulfate. Background technique [0002] Fluorine sulfur exchange (SuFEx) click reaction is a new generation of click chemistry reported by Professor Sharpless in 2014. The system uses cheap industrial insecticide sulfuryl fluoride (SO 2 f 2 ) react with phenolic compound to prepare the substrate of SuFEx click reaction. The synthetic polysulfate material has acid and alkali resistance, high glass transition temperature and excellent mechanical properties. [0003] High-valent main group fluorides have high chemical stability, but their activation under specific conditions can achieve extremely efficient chemical bond conversion and linkage. This special combination of stability and reactivity determines that this type of compound is in There will be unique potential applications in synthetic organic chemistry...
